+Once the west manifest has been updated, run west update, then patch the Zephyr tree (run inside the
+`zephyr` directory). The integration ships as two patches:
+
+- **`zephyr-tls-4.3.0.patch`** — the core wolfSSL backend (the BSD-sockets TLS layer and the
+  RNG/CSPRNG). This is all that is required to use wolfSSL for TLS sockets.
+- **`zephyr-tls-4.3.0-tests.patch`** — the wolfSSL twister test scenarios and the echo_server
+  sample overlay. Apply it only if you want to run the test suite yourself; it is not needed to
+  use the integration. It depends on the core patch, so apply the core patch first.
